- Аннотация: The storage of natural gas in an adsorbed state (ANG) in micropores is a way to increase the energy density and expand its usage for automotive vehicle applications. The performance of the ANG system is determined by an adsorbent. The granulated activated carbon prepared from coconut shell by steam activation was shaped into a monolith adsorbent by mixing with the polymer binder and compacting under 30 MPa. The shaping process improved the packing density of the activated carbon without noticeable degradation in its microporosity. The monolith adsorbent demonstrated high volumetric adsorption capacity combined with the fast rates of methane adsorption and remarkable cyclability. Thermodynamic analysis of methane adsorption at pressures up to 20 MPa and temperatures from 193 to 333 K made it possible to calculate the differential and integral isosteric heat of adsorption. These data were used for evaluating the heat effects in the ANG tank loaded with the monolith adsorbent and subsequent designing a prototype of the ANG system for NG-powered vehicles.
